With continued reference to fig. 2, a flow diagram of one embodiment of a blockchain transaction information management method according to the present application is shown. The block chain transaction information management method comprises the following steps:
s201, acquiring a current block height Hx and a local block height H, wherein the current block height Hx is the height of a block in a block chain account book when a Peer node is started, and the local block height H is the height of a block in a local account book when the Peer node is started;
the block height refers to the number of blocks linked to the main chain, that is, the total number of all blocks connected to the block chain, the block height is an identifier of the block, the block height indicates a specific position of a certain block in the block chain, a single block always has an explicit and fixed block height, when the current block height Hx is the Peer node, the height of the current block in the block chain account book, and the local block height H is the height of the block stored in the local account book when the Peer node is started.
It should be noted that the local ledger may be a local database, which may be a database that is pre-established and is used to store transaction information, the local database is connected to the above-mentioned blockchain network, and the local database may be any one of Mysql database, Oracle database, Sybase database, and the like, which is not limited herein.
In a further embodiment, the step S201 of obtaining the current block height Hx and the local block height H specifically includes the following steps:
when the Peer node is monitored to be started, a preset transaction total number state machine is operated to obtain the current block height Hx in the time zone block chain account book;
and acquiring the local block height H from the local book.
In this embodiment, a transaction total state machine is preset in each Peer node, and when it is monitored that the Peer node is started, the preset transaction total state machine is operated to obtain the current block height Hx in the block chain ledger, and meanwhile, the preset transaction total state machine obtains the local block height H from the local ledger so as to identify the synchronization state of the block chain ledger and the local ledger.
In this embodiment, the preset transaction total state machine refers to a Finite-state machine (FSM) used for determining whether a transaction total storage state between the blockchain account book and the local account book changes, and is a network virtual machine capable of identifying a Finite state and transitions and actions between the Finite state and the state.
S202, judging the synchronous state of the block chain account book and the local account book according to the current block height Hx and the local block height H;
the transaction total state machine can judge the synchronous state of the block chain account book and the local account book according to the current block height Hx and the local block height H, when the transaction total state machine judges that the current block height Hx is consistent with the local block height H, the synchronous state of the block chain account book and the local account book is determined to be synchronous, and when the transaction total state machine judges that the current block height Hx is inconsistent with the local block height H, the synchronous state of the block chain account book and the local account book is determined to be unsynchronized.
In this embodiment, a transaction total state machine preset at the Peer node judges a synchronization state between the block chain ledger and the local ledger according to the current block height Hx and the local block height H, and when the synchronization state between the block chain ledger and the local ledger is synchronized, that is, when the transaction total state machine judges that the current block height Hx is consistent with the local block height H, transaction total information stored in the block chain ledger is consistent with transaction total information stored in the local ledger, corresponding transaction total information can be read from the local ledger through a preset interface, and the read transaction total information is taken as a query result; when the synchronous state of the block chain account book and the local account book is unsynchronized, namely when the transaction total state machine judges that the current block height Hx is inconsistent with the local block height H, the transaction total information stored in the block chain account book is inconsistent with the transaction total information stored in the local account book, if the transaction total information of the local account book is read at the moment as an inquiry result, the inquiry result has an error, and therefore, when the synchronous state of the block chain account book and the local account book is unsynchronized, the transaction total information is not allowed to be directly read from the local account book through a preset interface.
It should be noted that there are three synchronization states between the block chain ledger book and the local ledger book, which are unsynchronized U, synchronized S, and synchronized and readable R, and the following is specifically described:
unsynchronized (U): when the Peer node is started, the transaction total information in the block chain account book and the transaction total information in the local account book are not synchronized, that is, the local block height H in the local account book is inconsistent with the current block height Hx in the block chain account book.
Synchronized (S): when the Peer node is started, the transaction total information in the block chain account book and the transaction total information in the local account book are synchronized, that is, the local block height H in the local account book is consistent with the current block height Hx in the block chain account book.
Synchronized and readable (R): under the condition that the transaction total information in the blockchain account book and the transaction total information in the local account book are synchronized, new transactions are generated on the blockchain in sequence, and the transaction total information in the block chain account book is continuously updated.
The synchronous state between the block chain account book and the local account book is judged by the transaction total state machine according to the current block height Hx and the local block height H.
In a further embodiment, the step S202 of determining the synchronization status of the blockchain ledger and the local ledger according to the current block height Hx and the local block height H specifically includes:
when the current block height Hx is 0, it is determined that the synchronization status is in synchronization and R can be read.
When the current block height Hx is larger than 0, judging whether the local block height H is consistent with the current block height Hx.
If the local block height H is consistent with the current block height Hx, the synchronization state is determined to be synchronized and readable R, otherwise, the synchronization state is determined to be unsynchronized U.
When the current block height Hx in the blockchain ledger is 0, it indicates that no transaction has been generated in the blockchain network, that is, there is no transaction record in the current blockchain ledger, the local block height H in the corresponding local ledger is also 0, the transaction total number state machine determines that the synchronization state of the blockchain ledger and the local ledger is synchronous and readable R, and continues to execute step S203; when the current block height Hx in the blockchain ledger is greater than 0, the transaction total state machine first determines whether the local block height H in the local ledger is consistent with the current block height Hx of the blockchain ledger, and when the local block height H is consistent with the current block height Hx, the transaction total state machine determines that the synchronization state of the blockchain ledger and the local ledger is synchronized and readable R, and continues to execute step S203; when the local block height H is not consistent with the current block height Hx, it is determined that the synchronization status of the blockchain ledger and the local ledger is unsynchronized U, and the following steps S301 to S304 are continuously performed, as shown in fig. 3.
S301, if the synchronization state is unsynchronized U, taking a block from the local block height H to the current block height Hx as a block to be synchronized;
s302, traversing all the blocks to be synchronized to obtain the transaction number of each block to be synchronized;
s303, accumulating the transaction number of each block to be synchronized and the original historical transaction total number information in the local account book to calculate new historical transaction total number information;
and S304, updating the new historical transaction total information to a local account book to replace the original historical transaction total information, and updating the synchronization state to be synchronized S.
When the transaction total state machine determines that the synchronization state of the blockchain account book and the local account book is unsynchronized U, the transaction total information is not allowed to be directly inquired through the local account book, and at the moment, the transaction total state machine is required to update the synchronization state and the transaction total information and then can inquire. Specifically, the transaction total state machine takes all blocks in the range from the height H of a local block in a local account book to the height Hx of a current block in a block chain account book as blocks to be synchronized, traverses all blocks to be synchronized to obtain the transaction number of each block to be synchronized, accumulates the transaction number of each block to be synchronized on the basis of the original historical transaction total information, namely accumulates the transaction number of each block to be synchronized and the original historical transaction total information in the local account book (the original historical transaction total information refers to the transaction total information calculated according to the transaction number of the height H of the local block in the local account book) to obtain new historical transaction total information, updates the new historical transaction total information to the local account book to replace the original historical transaction total information and updates the synchronization state to be synchronized S, and proceeds to step S203. It should be noted that, when the synchronization status is updated to be synchronized S, that is, the local block height H is consistent with the current block height Hx, the new historical transaction total information degree of the local ledger center is equal to the transaction total information calculated by the transaction number of Hx.
S203, if the synchronous state is synchronous and readable R or the synchronous state is synchronous S, monitoring the transaction in real time, and acquiring the transaction number of the new transaction when the new transaction is monitored to be generated;
when the synchronization state of the block chain account book and the local account book is synchronized S, the current block height Hx of the block chain account book is consistent with the local block height H of the local account book, and no new transaction is generated in the continuous monitoring process, namely, the transaction total number information in the block chain account book and the local account book is not changed in the real-time monitoring process; when the synchronization state of the blockchain account book and the local account book is synchronous and readable R, it indicates that the current blockchain height Hx of the blockchain account book is consistent with the local blockchain height H of the local account book, and in the continuous monitoring process, a new transaction occurs, that is, in the real-time monitoring process, the transaction total number information in the blockchain account book and the local account book keeps an updated state synchronously.
S204, calculating the current transaction total information according to the transaction number of the new transaction, and updating the current transaction total information to a local account book;
in the blockchain network, after each new transaction is completed, transaction information of the new transaction is recorded on a blockchain account book in real time, wherein the transaction information comprises transaction number, and the transaction total state machine calculates current transaction total information according to the transaction number of the new transaction in real time and updates the current transaction total information to a local account book.
In a further specific embodiment, the step S204 of calculating the current transaction total information according to the transaction number of the new transaction, and updating the current transaction total information to the local ledger specifically includes:
judging the synchronous state of the block chain account book and the local account book in the new transaction process;
if the synchronization state is synchronized S, reading historical transaction total information from a local account book;
accumulating the transaction number of the new transaction to the historical transaction total information to obtain new current transaction total information;
and updating the new current transaction total information to a local account book to replace the original current transaction total information, and updating the synchronization state to be synchronized and readable R.
